Abstract
The present invention provides a vehicle door, wherein a drive unit for raising and lowering a glass plate is constructed so that a plurality of pulleys across which wires are laid are provided at upper and lower sides of a base panel, the glass plate is moved up and down by driving the wires, the glass plate is prevented from moving in a vehicle inward direction when the door is closed, wire fixing portions are prevented from being damaged by great upward and downward stroke movements of the glass plate, and furthermore, the wires are prevented from slackening when the wires are driven and stopped. This is realized by providing a supporting rod along an upward and downward movement locus of the glass plate and a contact member which has no contact with the supporting rod, by forming trumpet-shaped guide portions at hole edges of the wire fixing portions, and by V-shaping the circumferential surfaces of a tensioner for eliminating slack of the wires.

4. A vehicle door attached to the getting in/out section of a vehicle in a manner enabling it to open and close, comprising:
-
a window at an upper side and a panel at a lower side, further comprising;
a glass plate which is movable upward and downward, and closes said door window when the glass plate rises, and is housed inside said vehicle panel when the glass plate falls, guide rails which are arranged at the front and rear sides of the upward and downward movement locus of the glass plate and guide the glass plate, and a drive unit which is provided inside the panel of the door and drives said glass plate up and down, where said drive unit for driving the glass plate up and down is provided with a base panel having a plurality of pulleys for guiding a wire for driving the glass plate up and down, a drum for driving the wire, provided on the base panel, a carrier plate constructed so as to move up and down between the upper and lower pulleys while supporting a lower side of said glass plate, and wires which are laid across the plurality of pulleys provided at upper and lower positions of said base panel, partially wound around the drum for driving said wires, and fixed to said carrier plate at ends, and furthermore, a tensioner which is provided between the pulleys and the drum, and tensions the wires to prevent the wires from slackening when the wires are about to slacken, and constructed so that the wires laid across the pulleys are moved by rotating said wire driving drum to drive the carrier plate up and down, wherein a main body of said tensioner is provided with a first slide member and a second slide member that are provided in parallel and connected to each other;
a gap for forming a passage for said wire is provided between the first slide member and second slide member;
the first slide member is pivotally attached to the base panel so that the second slide member can reciprocate like a pendulum, the circumferential surfaces of the first slide member and second slide member, which are opposed to the wire passing through the wire passage between said first slide member and second slide member, are almost V-shaped and provided with groove bottoms at which the wire passes through at centers, and in response to rotation of the drum having said spiral groove, even when a movement locus of the wire advancing and retreating between the drum and pulley deflects in a drum axial direction, the wire passing through said wire passage between the first slide member and second slide member always passes along the groove bottoms of the first slide member and second slide member. - View Dependent Claims (5)
